<p class="MsoNormal" style="margin-left:35.4pt">I have a Lustre 2.12 setup running on CentOS 7. It has been working fine for some months but last night one of my users tried to untar a large file, which (among other things) created a single directory containing
several million subdirectories. At that point the untar failed, reporting "no space on device". All attempts to create a file on this Lustre system now produce the same error message, but "df" and "df -i" indicate there is plenty of space and inodes left.
I checked the mount point on the metadata node and it appears to have plenty of space left too.<o:p></o:p></p>
